SEWER 'coNsTRUcTroN Y' 'e Y Original application led .Tuly 31, 1925,Serial No. 47,281. Divided and this application filed April 9,

The 'present invention relates to improvements in sewer constructionandconstitutesa division of my similarly entitled cio-pendingapplication, Serial No. 47,281, l filed July 31,1925. Y

An object of the invention described and claimed herein is to providetraps in the basin at points where the conduits connect with such basinfor the further purpose of check- 1-J ing the entrance into the conduitsfrom the basin of material which may clog the conduits. p 4

lVith the foregoing and otheriobjects in view, the invention will bemore fully del5 scribed hereinafter,- and will be more particularlypointed out in the claims appended l hereto.

In the drawings, wherein like symbols refer to like or correspondingparts throughout the 2U several views, l

vFigure l is a vertical sectional view of a basin, sewer and ltrapconstruction conforming to the present invention;

Figure 2 is a fragmentary elevation of the interior wall 1of a. basinAshowing a trap in closed position; y y

Figure 3 is a horizontal section taken on the line 3*?) in Figure 2; Y Y

Figure 4 is a view similar to Figure 2 but with the trap open;

Figure 5 is a. horizont-al section taken on the line 5 5 in Figure 4;

Figure 6 is a view on a reduced scale similar to Figure 4 showing'aperforated plate open .'15 and a plug inserted in a conduit;

Figure 7 is a vertical sec-tion taken on the line 7--7 in Figure 6; and

Figure 8 is a side View on an enlarged scale of a plug. n

Referring to the. drawings, and for the present to Figure l, 48, 48adesignates a perforated cover the horizontal part of which is shown asseated upon a shoulder 49 of the horizontal `part of frame 50. Thefra-me 5() Vis shown as fitted upon the. upper end of the wall 51 of abasin 52. The vertical part 48a of the cover will extend up within anopening in the curb. The horizontal part 48 of the cover is shown asprovidedwith trunnions ao adapted to enter suitable slots in thehorizontal part of the frame 50. The curb is shown as provided with acut out portion 54. By raising the horizontall part 48 of the cover thecover as a whole may be rocked on'the 65 trunnions and the opening intothe receiving basin uncovered. 'Y yWhen the horizontal part of the coverhas beenrocked sufiiciently far it will rest against the curb. Theraising up of the horizontal. part- 48 will cause the vertical lpart48'Ll to move in Vthe cutout portion 54 and this cutout portion 54 willbe so shaped as not to interfere with the movement of lthe vertical part48a therein. While Ihave shown the cover 48, 48a as'circ-ular'in shapeitwill, of course, be readily understood that the cover may be of anydesired shape', in which case the frame may be madeto conform to theshape of the cover. L

It will, of course, be vunderstood that` as much of the basin as may bedesired maybe built under the sidewalk,` leaving only, if desired, anvopening in Vthe street sufiiciently large to permit an operator toenter the basin, and, if desired, instead of havingy a perforated coverof the type shown inthe drawings any be provided.` f l l Within thebasin 52 is shown a ladder 55 appropriately supported to enableoperators to rdescend into the basin when the i cover thereof is lifted.Pipes 59,v 60 and. 6,1 are shown as leading downwardly and outl'of theba'sinf52 at various elevations.V Apipe yi61is shown as leading into thepipe and may be a V-shaped pipe if desired. Thispipel 60 is shown asconnecting with a sewer indicated at'62. A pipe 63 is shown as leadingdownwardlyand into the basin 52 and may carry. fluid from another'basinA or-any higher leve The pipes 60 and 61 may be made in one pieceif desired. f

A sewer 62 is shown as provided with a guard 64, this guard being shownas in the shape of a perforated door hinged at its up- 1 per end asindicated at 65 and adapted to abut at its lower end against a. stop 66whichwill restrict swinging movement of thedoor to maintain the dooracross the sewer and arrest large material passing through the sewer.Y Ahook 67 is shown aspivotally mounted in the sewer at an appropriatepoint to engage with an eye 68 on the door 64, whereby to hold the doorelevated when its use is not desired. In!

be provided to restrict swinging movement of the door and any desiredmeans might be employed to hold the door open. The space in the sewer infront of thedoo-r 64 is accessible through a manhole 68, in which isshown as placed a ladder 69, 'the manhole being n suitable opening andcover to the basin may stead of they stop GGany suitable means maydesignates the side l .o shown ,as hinged upon` door 184, beingfshovvn.nearly am'eterlas azpipe indicated at 87' infFigures shown-as closed.the surface `cov-er An extension ladder 71 may be provid ed to let downinto the sewer from the man-hole.

The guard`64 is desirable fordiseoveringf 1 bodies that may haveentereda sewer and for locating the approximate points at'or aboutwhich, these bodies entered thesewer. AReferring toV Figures 2 toinolsive,"51 wall of a basin in `which a trap is mounted. This trap isshown as con sisting of aI plate 83 `shown as mounted flush in thefwall51` This plate may servetas ari attaching base fory a perforated door 84an elongated pintle 85.
